SFM Series Automated and Programmable Functionality

The SFM Series Solar Powered Fuel Maintenance and Tank Cleaning Systems are programmable, fully automated Fuel Maintenance Systems that remove water, sludge and contaminants wherever fuel is stored or used. SFM Systems are designed to optimize and maintain diesel fuel indefinitely by removing particulate and water in stored fuel. At times, the location where this all must occurs is not near a connection to the grid, and often there is nobody around to start the generator. But the process of polishing diesel fuel still needs go forward and the fuel tank, in order to maintain the fuel in a condition so it is ready when the need arises, must be cleaned.

Powered by a solar panel, this innovative process stabilizes diesel and bio-fuels, eliminates microbial contamination, and ensures clean reliable fuel at all times. The SFM Series Solar Powered Fuel Maintenance System is ideal for stored fuel in remote locations where power is not readily available.

The SFM Series Fuel Maintenance and Tank Cleaning Systems feature:

All FPS Systems feature:

  • Compact Industrial Lightweight Design


  • SMART Solar Controllers


  • Fully Automated Operation


  • Unique Safety & Alarm Features


  • Discreet Alarm Indicator Lights


  • Continuous-Duty Pumps, Viton Seals


  • NEMA Rated Weatherproof Enclosure

An SFM Series Fuel Polishing System is the central component of a Fuel Management Plan for installations that operate in a remote area infrequently, but must be called on, and relied on, when the need arises. Establishing a fuel management and maintenance protocol for these systems should include removal of accumulated water, periodic fuel circulation for particulate filtration and polishing of the fuel, and treatment with a Diesel Fuel Catalyst made to work hand-in-glove with the Fuel Polishing System to clean the fuel tank without removing the fuel, assuring that the lights stay on when the power goes off.

Applications

A fuel storage tank located in a remote location can be a challenge to maintain. A wilderness fishing or hunting camp may be used only a few times each year, and the fuel in the tank that powers the generator is there all year, and, without attention, the degradation of the fuel and infiltration of water and contamination is going on without notice. When the generator is started, it runs for twenty minutes and then shuts down. Clogged fuel filter!

Center Pivot Irrigation

Or a diesel engine is on standby to power a pump that pumps water from a nearby water source or well to feed a center pivot irrigation system that covers hundreds of acres. The irrigation system has not operated since last season, but the fuel tank has been full of fuel. When the motor is called upon, again, clogged fuel filter!

Other agricultural applications include remote water sites for cattle Crop Wind Machine Power

These situations are much too common. Oil or gas pumps located far afield need to be ready when called upon. Wind machines that protect orchards and growing fields now are commonly equipped to start automatically when temperatures drop and need to have a ready source of power when called upon. Depending on a generator powered by fuel that has not been used since last season (or the season before) is a recipe for disaster.

While some folks like to have diesel fuel on hand for when they need it, others today are keeping some in a tank for when it may not be available. Preppers and those in the survivalism movement go to great lengths to be prepared for the unknown and the unforeseen. Now fuel can be maintained and kept in optimal condition for the long term without the need to be on-site to start the generator just to polish your diesel fuel.

Diesel fuel is often the fuel source of choice in applications requiring generated power over wide geographic areas. Large farm operations need to power water pumps on short notice to provide water for irrigation and to fight damage from frost conditions. Often these pumps are in stand-by mode for extended periods. A fuel tank may sit in the sun and be subject to extreme temperature variances that cause the formation of condensation in tanks, providing the perfect habitat for microbial and fungal growth. Long periods when equipment remains idle allows for the infestation to develop and, when conditions demand the pump be ready to serve, the need is not met due to clogged filters and fuel that is in such a condition that prevents efficient operation of the diesel engines.

Remote monitoring services are widely available to tell you that your remote generator has failed to perform a test start up or is not operating when the need for reserve power arises, but that is of little help when the cause of the failure is contaminated fuel, clogged fuel filters, and mechanical failures caused by fuel that has gone bad. Maintaining fuel in optimal condition is necessary and is assured with the use of the AXI® Solar Powered SFM-1080.

SFM 1080 Functionality

The SFM 1080 Solar Powered Fuel Maintenance System is designed and constructed to be located wherever the fuel tank sits.

To ensure safe operation, the SFM 1080 System will shut down the pump and illuminate an alarm light whenever a fault condition occurs. Fault conditions that trigger pump shut down are: filter servicing is required (high suction level), high water level in the separator bowl, or a leak is detected in the fuel containment tray. In addition, the pump motor is protected from overload by a resettable circuit breaker/switch.

The FPS Compact system is automatically operated by the programmable control panel. The controller’s alarm functions and pump shut-down are triggered if filter elements require service, if high pump vacuum, leak detection or if there is water in the separator. The wiring harness with plugs easily connects the SMART Filtration Controller with the FPS allowing for greater flexibility in installation and access where it’s most convenient.

The principal components of the FPS Compact system are a continuous-duty pump with primary filter/water separator with vacuum sensor and gauge, an ALGAE-X Fuel Conditioner and a SMART Filtration Controller. The SEPAR primary filter protects the pump, coalesces and removes water and particulate. The patented AXI Fuel Conditioner prevents and reverses fuel degradation, agglomeration and microbial contamination.

SFM Series Systems are designed around a self-priming 80 GPH nickel-plated brass gear pump. Quality filtration components are connected using corrosion-resistant Stainless Steel plumbing. A pressure gauge is installed on the filter housing to monitor back pressure indicating a filter is holding particulates sufficinet to cause a flow restriction, alerting to the need to change out the filter.

AXI Fuel Conditioner

The fuel flow first enters the FPS DX-S System through the AXI Fuel Conditioner. Operating on the principal of induction on the process of combining kinetic and magnetic energy to influence the behavior of electrons, the AXI Fuel Conditioner provides a powerful magnetic field and the flow of fuel provides the kinetic energy.

As fuel deteriorates, clusters of fuel components break down and residue begins to accumulate, resulting in dark, hazy fuel with poor combustibility. The increase in size and mass of the fuel breakdown products lead to clogged filters and the build up of tank sludge. The AXI Fuel Conditioner dissolves the clusters, stabilizes the fuel, and eliminates tank sludge. The results are Clear & Bright Fuel, improved filterability, optimal combustion and clean fuel systems. The process of how the AXI Fuel Conditioner makes clear, bright and more combustible fuel as well as restoring degraded fuel and eliminating the effects of microbial contamination is compelling. As the AXI Fuel Conditioner does not filter the fuel, but treats it as it passes through the unit, there is seldom any reason to suspect that a restriction is in the AXI Fuel Conditioner. But you can remove the face plate, remove the magnet and wipe it off with a shop rag and replace the filter and face plate. A spare parts kit for the AXI Fuel Conditioner includes a new face panel O-Ring and replacement screws to fasten the face plate.

Primary Filtration

TK-070 Strainer

The primary filter is a 50 mesh T-Screen that is designed to protect the fuel pump from foreign material that may be picked up in the suction and to remove larger sludge and debris that may damage the pump or shorten the life of the secondary filter. The T-Screen is easily disassembled and cleaned.

Secondary Filtration

WBS-3 Water Block Filter Element

The FPS DX-S Secondary Filter is a spin-on filter. The filter housing includes a gauge that reads the back pressure and, when the back pressure increases indicating that the flow of fuel is being restricted by the accumulation of particulates or other debris on the filter element inside the spin-on filter, it is time to change the filter. This assures that you are not leaving a filter on too long, compromising the filtration process, or changing the filter too soon and not receiving all the value for the filter and increasing your operating costs.

AXI recommends the use of the FFS-10 Particulate Filter, a 10 micron filter element, or the WBS-3 Water Block Filter, a 3 micron filter element. Both are spin-on secondary filter elements. The Water Block filter is usually the preferred filter as it will remove free water and emulsified water from the fuel stream along with the removal of particulates. Most engine manufacturers want the fuel entering their engine to be filtered at 4 microns, removing particulates and organic debris from the fuel preventing these contaminants from causing problems with the tolerances of fuel injector systems. Although modern engines have a factory-provided filter, usually in the 4 micron range, supplying fuel to the filter that already meets these requirements will extend the life of the factory filter and also assure the fuel is in optimal condition for use in these highly developed injector systems.

The System Controller

The Programmable Digital Timer offers a variety of weekly programs. It is equipped with a replaceable battery to retain the program and memory backup. After setting the clock and timer, the Programmable Digital Timer will operate on the schedule you set, and will shut down and provide an alert in the event of high vacuum, high exit pressure, or as a result of receiving a signal from the float switch, located in the tray, that an accumulation of fluid has occurred.

A vacuum switch is positioned between the primary filter/screen and the pump to sense if the primary filter is clogged, thereby restricting the flow of fuel to the pump. A pressure switch is positioned between the pump and the secondary spin-on filter to sense if the pump is pushing fuel to a restricted or clogged secondary filter. Any excessive vacuum on the suction side of the pump, or excessive pressure on the pressure side of the pump will alert the controller to the need for filter maintenance and shut down the system to assure that the condition does not cause damage to components.

A float valve is installed in the base of the cabinet to sense if an accumulation of fuel may occur caused by a leak or other component failure, automatically stopping system operation.

The Solar Charge Controller and Solar Panel Battery Regulator will automatically manage the solar panel and battery, providing overloading and short-circuit protection, featuring reverse discharging and reverse-polarity protection, and under-voltage and over-charging protection.

The SMART Solar Controller includes a timer controller and sensors to shut down in the event of high vacuum, high pressure or leak detection.

The entire package is contained within a NEMA Rated Weatherproof Enclosure including locking hinged front door.

Recommended Tank Cleaning & Fuel Treatments

AFC-705 Diesel Fuel Additive

It is recommended that diesel fuel be treated with the AXI Fuel Catalyst AFC-705 (for pre-2007 engines) or AFC-710 (Tier 4 compliant) Diesel Fuel Catalyst prior to the initial tank cleaning and at least every six months thereafter to assure the fuel tank remains clean and the fuel is stabilized. This will enhance and accelerate the tank cleaning process by breaking down and dissolving existing tank sludge. Always check the fuel tank for an accumulation of water in the bottom of the tank. Using a rod, sometimes used to measure fuel in a storage tank, or a length of PVC pipe, spread a line of Kolor Kut Water Finding Paste on the side of the rod or pipe and insert to the bottom of the tank. If the paste touches water, it will change colors, showing how much water is in the tank requiring removal.

AFC-710 Diesel Fuel Additive

Pump accumulated water out of the tank for proper disposal. It is often the case that all of the water is impossible to remove. AFC-705 contains a surfactant that will emulsify the residual water up into the fuel for removal by a Water Block Filter on the AXI Fuel Polishing System AFC-710 does not include this surfactant component). Depending on the condition of the fuel and the amount of sludge build-up, it is recommended to initially use a double dose of one to twenty-five hundred (1:2500 - one oz. to 20 gallons of fuel) and circulate the capacity of the tank five times. Always treat the tank when the tank is full of fuel. If you perform a treatment with a half tank of fuel, you will only be cleaning the bottom half of the tank. The use of AXI Fuel Catalyst has proven to be essential in accelerating the tank cleaning process. AFC-705 and 710 contains detergent, dispersant, corrosion inhibitor, lubricity enhancer and combustion catalyst. AXI Additives do not contain biocides.

AFC-710 Powder Diesel Fuel Additive

For engines manufactured in 2007 and later, use AFC-710, available in both liquid and powdered form. AFC-710 does not contain the surfactant (used to emulsify residual water into the fuel for removal in the circulation process as does AFC-705), a component that does not allow for qualification as a Tier 4 product. AFC-705 and AFC-710 should always be used periodically in particular to stabilize fuel that is stored for longer periods of time.

After the initial cleaning, the AFC-705 or AFC-710 in the fuel will continue to stabilize the fuel for six months or more. Every six months, or more often if the region in which you reside is a humid climate, treat the fuel again and circulate the capacity of the tank three times. In applications where fuel from a treated tank is distributed to other equipment, the additive will also clean the downstream tanks and continue to stabilize the fuel.

AFC-710 Powder

Tank Cleaning & Fuel Treatment for Cold Weather Use

For cold weather operations, AXI Fuel Catalyst AFC-805 is a unique and powerful anti-gelling broad-spectrum fuel additive specifically formulated for use in Diesel, Bio-fuels, Gasoline, Kerosene, and HFO. AFC-805 should be used as part of any preventative fuel maintenance program, and is ideal for use in bulk storage fuel tanks in cold weather environments. AFC-805 enhances the breakdown and removal of sludge, slime, and bio-fouling from tank walls and baffles that are difficult to access.

AFC-805 effectively decontaminates and cleans an engine&rsquot;s entire fuel and injection system. It continues to work in storage tanks cleaning and stabilizing fuel for up to 12 months with a single dose. AFC-805 is ideally used for cold weather applications where there is long term fuel storage, such as bulk fuel farms, winterized recreational and work boats, and also smaller engines. AFC-805 is recommended at a ratio of 1:5000 (one oz of AFC-805 to 40 gallons of fuel)

The Following Guides
Tell the Story

Fuel Management System Operation

The fuel you depend on should always be in optimal condition. Periodic circulation of fuel assures optimal combustibility and fuel cleanliness. All major diesel engine manufacturers have set minimum fuel standards for the diesel fuel to be used in their engines, and failing to maintain fuel that meets those standards could lead to engine component failures and denied warranty claims. As an example, Caterpillar has published "Cat Commercial Diesel Engine Fluids Recommendations" (SEBU6251-17 September 2014 [a more recent version may be available]) that states "In order to meet expected fuel system component life, 4 micron(c) absolute or less secondary fuel filtration is required for all Cat diesel engines that are equipped with common-rail fuel systems." (Page 34) You should not assume that fuel being delivered to you meets the engine manufacturer’s requirements, and certainly fuel that has been in your storage tank for an extended period of time is unlikely to meet requirements of diesel engine manufacturers without a Fuel Management Program.

Cleanliness standards for diesel fuel, established in the late 1990&rsquot;s by the International Organization for Standardization (ISO), apply to diesel fuel. Caterpillar recommends that the fuel dispensed into the machine tank meets "ISO 18/16/13" cleanliness level." (Page 49) For more information on fuel cleanliness specifications and what those requirements mean to you, review the "Diesel Fuel & Injector Failure" web page on this site.

Continued vigilance to assure that your fuel is in the best condition possible and always meets the requirements to maintain engine manufacturer's warranty requirements is a major challenge without the use of an AXI Fuel Conditioning & Tank Cleaning System to address the need for periodic Fuel Polishing.

Fuel Maintenance Plans

Clogged Fuel Filter

A Fuel Maintenance Plan should be a part of every periodic engine Preventative Maintenance Program. Preventative Maintenance Programs are common in all major industries today, but monitoring the fuel condition is often taken for granted and not included in the Preventative Maintenance Program. Many of today's maintenance personnel have many years of experience, but until changes in sulfur content in diesel fuel were regulated within the past decade, and with the government&rsquot;s push for blending some amount of bio-diesel into regular diesel fuel, maintenance professionals were never presented with the problems that we are experiencing today. With today&rsquot;s advances in design and engineering of diesel engines, especially the new fuel injection systems, and with more emphasis being placed on critical requirements that equipment have longer life cycles and near 100% uptime, fuel management can no longer be ignored. It is now just as important as changing the oil, ensuring the batteries are charged, and the air filter is clean.

Service Agreements with an outside contract company to perform Preventative Maintenance typically do not cover fuel-related management and monitoring unless specified. In-house maintenance personnel are usually pressed for time, and fuel management can be easily glossed over. Fuel has a limited shelf-life and even "fresh fuel" could contain water, sediment, microbes, asphaltene agglomeration, or other contaminate components upon delivery and cause immediate engine performance issues.

Emergency power installations are especially susceptible to unexpected interruptions due to fuel related issues. Periodic generator tests-runs are too short to determine if fuel quality is adequate for the demands of continuous, full-load operation. In fact, generator test runs have been found to significantly accelerate the fuel polymerization and degradation process, resulting in the accumulation of gums and resins in the fuel system, by returning fuel that has been compromised by heat and pressure back to the tank. Thirty minute tests, often performed every month, create the environment in the tank for problems to grow. After extended periods of testing, sometimes years, without having been subjected to an extended full load, operation is interrupted by clogged filters when the lights go out.

Now that you have decided to institute a Fuel Management Plan for your operations, there is work to do. Consider the following as the basis for your Fuel Management Program to further assure that your equipment will run when it is needed most at it&rsquot;s peak level of performance and repair costs will remain under control:

  • Place in service an AXI Fuel Treatment & Tank Cleaning System appropriate to your operations that are capable of performing a complete tank cleaning and fuel conditioning on each fuel tank in service at least once per year (more often in regions of high humidity). Evaluate what other aspects of fuel monitoring and testing is needed to assure that critical equipment needs, including down-stream equipment, may need to be included in your Fuel Management Plan.

  • Use AXI Broad Spectrum Fuel Catalyst Ultra Concentrate AFC-705 or AFC-710 every six months to enhance the breakdown and removal of sludge, slime, gums, resin, and bio-film from tank walls and baffles that are difficult to access and normal fluid flow does not break loose. Having this unique fuel additive present when fueling downstream equipment also assures that these downstream tanks are being cleaned in the normal course of operations (although separate water removal will be necessary).

  • Periodically (every 30 to 60 days, depending on your climate) use a Fluid Sampler or a hand Fuel Sample Pump to take samples of your fuel from each storage tank and critical equipment fuel tanks for in-house testing for acidity (pH) and use Liqui-Cult Fuel Test Kits to perform testing for microbial contamination. If initial tests indicate fuel problems, utilize laboratory analysis to evaluate the condition of your fuel to assure your fuel supplier is providing fuel that meets the specification of the engine manufacturer you depend on to keep your equipment running.

  • Use a Portable Particle Counter to test each incoming load of fuel to assure that the cleanliness of fuel provided by your supplier meets the specifications established by the manufacturers of the engines that power your equipment. Your engine warranty depends on it!

  • If the quality of your fuel is suspect, consider establishing a quarantine tank to accept new shipments (do not add new shipments of fuel to your stored fuel that has been de-watered and to which you have performed fuel polishing, and is known to meet your Fuel Management protocols).

  • Use Kolor Kut Water Finding Paste at least every 30 to 60-days to monitor the accumulation of water in your storage and equipment fuel tanks due to condensation or from fuel fills. If any amount of water is detected, take steps to remove it.

  • Install Desiccant Breathers on all your fuel storage tanks to help prevent moisture from entering your tanks through the vent as fuel is consumed.

  • Use Water Eliminators in each storage and equipment fuel tank to capture water and remove it before it can cause problems with engine operations or seasonally prevent water from freezing in fuel lines?

With only moderate effort, you can be assured that your diesel fuel will provide optimal performance and enjoy the expected life of your engine’s fuel filters, fuel system components, and your substantial investment in the diesel engine.
